Abstract

The invention relates to a control and energy supply system for the drive units and control units for at least two, preferably adjacent, aircraft seats, whereby all system components are connected by means of a data bus, such that the control system of the one seat is informed of what is happening to the other seat. The adjuster motors of the seats are supplied with electricity by means of two distinct networks. System breakdowns caused by loose or disconnected connectors, broken cables, short circuits and faulty controllers are thus avoided by said redundancy concept.

Description

Steuerungs- und Energieversorgungssystem für wenigstens zwei FlugzeugsitzplätzeControl and power supply system for at least two aircraft seats
Die Erfindung betrifft ein Steuerungs-, Energieversorgungsmangement und ein „Power-Sharing"-Konzept für die Antriebe und Steuereinheiten in Flugzeugsitzen.The invention relates to a control, energy supply management and a “power sharing” concept for the drives and control units in aircraft seats.
Bei den Steuereinheiten, Antriebseinheiten und sonstigen Konfigurationsände- rungselementen eines Flugzeugsitzes können folgende schwerwiegende Fehler auftreten: Lose oder abgefallene Steck- oder sonstiger Verbinder, Kabelbruch, Kurzschlüsse zu Masse oder einer anderen Versorgungsleitung, ausgefallene Steuereinheiten sowie der Ausfall von Antriebseinheiten oder Eingabegeräten bzw. Bedienungselementen, bei denen es sich beispielsweise um Taster, Schalter, Chipkartenleser evtl mit einem Display handeln kann.The following serious errors can occur in the control units, drive units and other configuration change elements of an aircraft seat: loose or dropped connectors or other connectors, cable breaks, short circuits to ground or another supply line, failed control units and the failure of drive units or input devices or operating elements, which can be, for example, buttons, switches, chip card readers with a display.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein System anzugeben, bei dem die Funktion der Steuereinheiten, Antriebseinheiten, bzw. sonstiger Konfigu- rationsänderungselemente sichergestellt ist.The present invention is based on the object of specifying a system in which the function of the control units, drive units or other configuration change elements is ensured.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale der unabhängigen Patentansprüche gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.This object is achieved by the features of the independent claims. Advantageous embodiments of the invention are characterized in the dependent claims.
Die Erfindung sieht ein Redundanzkonzept vor, das fehlertolerant ist. Vorteilhafterweise wird das Konzept durch ein „Power-Sharing und Managemenf-System zur Anpassung an die jeweiligen Steuerungsanforderungen ergänzt, wobei es sich hierbei um einen sehr wesentlichen, eigenständigen Erfindungsgedanken handelt.The invention provides a redundancy concept that is fault tolerant. The concept is advantageously supplemented by a “power sharing and management system for adapting to the respective control requirements, which is a very essential, independent inventive idea.
Das erfindungsgemäße System besteht aus einer für den jeweiligen Flugzeugsitzplatz angepaßten Anzahl von Antriebseinheiten, Steuereinheiten und Überwachungseinheiten, wobei diese Elemente von wenigstens zwei vorzugsweise benachbarten Flugzeugsitzplätzen bevorzugt in Form einer Bus-Struktur oder Ring- Struktur angeordnet sind. Das System kann aber auch die Elemente von drei oder mehr Flugzeugsitzplätzen umfassen.The system according to the invention consists of a number of drive units, control units and monitoring units adapted for the respective aircraft seat, these elements of at least two preferably adjacent aircraft seats preferably being arranged in the form of a bus structure or ring structure. The system can also include the elements of three or more aircraft seats.
Die Bus-Struktur kann ein Ringsystem oder auch ein lineares System sein. Bei linearen Strukturen werden bevorzugte Doppelbusse verwendet, die antiparallel verlegt werden.The bus structure can be a ring system or a linear system. In the case of linear structures, preferred double buses are used, which are laid antiparallel.
Eine andere, z. B. diskrete Anordnung der Eingabe - bzw. Bedienungselemente ist auch möglich.Another, e.g. B. discrete arrangement of the input or control elements is also possible.
Die Steuereinheiten und die Antriebseinheiten der aus zwei oder mehr Flugzeugsitzplätzen bestehenden Sitzgruppe sind mit einer lokalen Intelligenz ausgestattet, die ständig die Konfiguration an die überwachenden Systemteile übermittelt, wobei die Einheiten z.B. mit geeigneten Sensoren ausgestattet sind. Die Steuereinheiten haben einen Bus-Controller. Die Bus-Controller von wenigstens zwei Steuereinheiten sind über die Konfigurationsmeldungen über alle Vorgänge in dem System informiert.The control units and the drive units of the seating group consisting of two or more aircraft seats are equipped with local intelligence which constantly transmits the configuration to the monitoring system parts, the units e.g. are equipped with suitable sensors. The control units have a bus controller. The bus controllers of at least two control units are informed of all events in the system via the configuration messages.
Die Steuereinheit und die Antriebseinheiten eines Flugzeugsitzplatzes sind in der Weise mit der Steuereinheit und den Antriebseinheiten wenigstens eines weiteren Flugzeugsitzplatzes bevorzugt über ein,e Bus-Struktur oder Ring-Struktur derart verbunden, daß jede Antriebseinheit über zwei Verbindungen von den zugehörigen beiden Steuereinheiten ansteuerbar ist. Wenn die normale Bus-Verbindung zwischen einer Antriebseinheit und der zugehörigen Steuereinheit des Flugzeug¬ sitzplatzes unterbrochen ist, wird dies über die lokale Intelligenz der Systemkomponenten festgestellt und der anderen Steuereinheit gemeldet, über deren Bus- Verbindung die betroffene Antriebseinheit dann angesteuert wird.The control unit and the drive units of an aircraft seat are in the Connected to the control unit and the drive units of at least one further aircraft seat, preferably via a bus structure or ring structure, in such a way that each drive unit can be controlled by the associated two control units via two connections. If the normal bus connection between a drive unit and the associated control unit of the aircraft ¬ seat is interrupted, this is determined through the local intelligence of the system components and the other control unit reported, the drive unit concerned is then controlled via the bus connection.
Außerdem sieht die Erfindung vor, daß jede Antriebseinheit der beiden oder mehr Flugzeugsitzplätze von wenigstens zwei Netzgeräten mit Strom versorgbar ist. Wenn die lokale Intelligenz in den Systemkomponenten feststellt, daß der normale Strompfad eines Flugzeugsitzplatzes unterbrochen ist - wie dies bei einer abgefallenen Steck- oder sonstigen Verbindung sowie bei einem Kabelbruch in der Stromversorgung der Fall ist - wird dies über das Bus-System an die beiden Steuereinheiten gemeldet, woraufhin die Ansteuerung dann so erfolgt, daß der Strom vom Partnersystem übernommen wird. Dabei erfolgt vorzugsweise eine Stromvorausberechnung, um so sicherzustellen, daß die Partnerversorgung nicht überlastet wird.In addition, the invention provides that each drive unit of the two or more aircraft seats can be supplied with power by at least two power supply units. If the local intelligence in the system components determines that the normal current path of an aircraft seat is interrupted - as is the case with a broken plug or other connection and a cable break in the power supply - this will be sent to the two control units via the bus system reported, whereupon the control then takes place so that the current is taken over by the partner system. In this case, a current prediction is preferably carried out in order to ensure that the partner supply is not overloaded.
Bevorzugt ist vorgesehen, daß die Stromversorgungsleitungen nur bei Bedarf mit Strom versorgt werden. Das bedeutet, daß im Falle eines Kurzschlusses zunächst keine Reaktion stattfindet. Die in die Steuereinheit eingebaute Kontrolleinrichtung (CBIT = Continuos Built In Test) bestromt aber in Abständen für kurze Zeit von beispielsweise 100 ms die Versorgungsleitungen, um z.B. die Elektronik der Antriebseinheiten zu versorgen, aber auch um zu prüfen, ob ein Kurzschluß im Leitungssystem vorliegt. Wird ein Kurzschluß festgestellt, wird auf die alternative Stromversorgung des Partnersystems umgeschaltet.It is preferably provided that the power supply lines are supplied with power only when required. This means that in the event of a short circuit, there is initially no reaction. The control device built into the control unit (CBIT = Continuos Built In Test), however, energizes the supply lines at short intervals of, for example, 100 ms in order to e.g. to supply the electronics of the drive units, but also to check whether there is a short circuit in the line system. If a short circuit is detected, a switch is made to the alternative power supply of the partner system.
Alternativ kann eine konstante Stromüberwachung erfolgen, wobei im Fallle einer Überschreitung eine Abschaltung erfolgt. Entsprechend der vorstehenden Beschreibung kann das Vorhandensein einer ungewollten Fremdversorgung beispielsweise aus dem 28 V-Flugzeugbordnetz erkannt werden. In diesem Fall werden die Systemteile angewiesen, nur noch auf die Partnerversorgung zu reagieren.As an alternative, constant current monitoring can take place, with a shutdown taking place in the event of an overshoot. According to the above description, the presence of an unwanted external supply can be recognized, for example, from the 28 V aircraft electrical system. In this case, the system parts are instructed to only react to the partner supply.
Wenn es zu einem Kurzschluß zur Masse oder zur Versorgung des Bus-Systems kommt, ist die Bus-Komunikation gestört. Dies wird sofort bemerkt und auf das Partner- System umgeschaltet.If there is a short to ground or to the bus system, the bus communication is disrupted. This is noticed immediately and switched to the partner system.
Gemäß der vorliegenden Erfindung kann auch der Ausfall einer Steuereinheit kompensiert werden. Der Status jeder Steuereinheit sowie die Anforderungen an die Steueraufgabe werden zwischen den Steuereinheiten ausgetauscht. Der Status wird dabei auf der Basis des CBIT zusammengestellt und kommuniziert. Bleibt eine plausible Information einer Steuereinheit aus, übernimmt die andere Steuereinheit die Aufgaben des Partners. Das „Power-Management" in der Steuereinheit stellt dabei sicher, daß die Stromversorgung nicht überlastet wird. Wenn nur die Steuereinheit ausgefallen ist, kann die Stromversorgung weiter genutzt werden.According to the present invention, the failure of a control unit can also be compensated for. The status of each control unit and the requirements for the control task are exchanged between the control units. The status is compiled and communicated on the basis of the CBIT. If there is no plausible information from one control unit, the other control unit takes over the partner's tasks. The "power management" in the control unit ensures that the power supply is not overloaded. If only the control unit has failed, the power supply can continue to be used.
Der Ausfall einer einzelnen Antriebseinheit oder eines Bedienungselementes ist nicht auszuschließen. Da diese Geräte im allgemeinen nicht doppelt vorhanden sind, muß dieser Ausfall toleriert werden. Für solche Zwecke sind bei den Antriebseinheiten bzw. Stellsystemen manuelle Rückführungseinrichtungen vorhanden. Im Falle des Eingabegerätes bzw. Bedienungselementes kann aber das Gerät des Partners benutzt werden. Die Funktion aller anderen Systemkomponenten ist von solchen Fehlern nicht betroffen.The failure of an individual drive unit or an operating element cannot be ruled out. Since these devices are generally not duplicated, this failure must be tolerated. For such purposes, manual feedback devices are available in the drive units or control systems. In the case of the input device or control element, however, the partner's device can be used. The function of all other system components is not affected by such errors.
Im Bereich der Flugzeugsitze muß eine Vielzahl von Geräten mit Strom versorgt werden. Hierbei handelt es sich z.B. um ein Video-Unterhaltungssystem, ein Telefon und einen Internetzugang, die Versorgung für einen PC (Laptop) um Leselicht und die Sitzsteuerung. Bedingt durch die Menge der Flugzeugsitzplätze ist der Strom pro Sitzplatz zwangläufig limitiert. Die vorliegende Erfindung nutz die Querverbindung zwischen den Sitzplätzen, um dem einzelnen Sitz mehr Leistung anzubieten, als dieser normalerweise unter „Worse-Case"-Betrachtungen erhalten kann. Da der momentan verbrauchte Strom des oder der Partnersitzplätze bekannt ist, läßt sich über die Verbindungsleitungen diese Leistungserhöhung realisieren.In the area of the aircraft seats, a large number of devices must be supplied with electricity. This includes, for example, a video entertainment system, a telephone and Internet access, the supply for a PC (laptop), reading lights and seat control. Due to the number of aircraft seats, the electricity per seat is inevitably limited. The present invention uses the cross-connection between the seats in order to offer the individual seat more power than can normally be obtained under "worse-case" considerations. Since the current of the partner seat or seats currently used is known, this can be done via the connecting lines Realize performance increase.
Außerdem sieht die Erfindung vor, daß in Hochleistungsfällen unwichtigere Versorgungen automatisch abgeschaltet werden. Ein besonderer Fall ist dabei die Forderung, den Sitz aus allen Konfigurationen in 15 Sekunden in die Landekonfiguration zu fahren. Berechnungen zeigen, daß in einem solchen Fall die Leistungsangebote nicht ausreichen.In addition, the invention provides that less important supplies are automatically switched off in high-performance cases. A special case is the requirement to move the seat from all configurations to the landing configuration in 15 seconds. Calculations show that the range of services offered is not sufficient in such a case.
Die vorliegende Erfindung beinhaltet die Möglichkeit, zunächst unnötige Verbraucher abzuschalten. Hierbei kann es sich z.B. um das Leselicht, das Video oder um den PC handeln.The present invention includes the possibility of first switching off unnecessary consumers. This can e.g. the reading light, the video or the PC.
Ergänzend wird erfindungsgemäß auch das oder die Partnersysteme befragt, welche Strommengen zur Unterstützung bereitgestellt werden können. Bei einer solchen „Notanfrage" werden auch bei dem Partnersystem die unnötigen Verbraucher abgeschaltet.In addition, according to the invention, the partner system or partner systems are also questioned as to which amounts of electricity can be provided for support. In the case of such an "emergency request", the unnecessary consumers are also switched off in the partner system.
Gemäß der vorliegenden Erfindung können die vorgegebenen Limits sowohl im Bereich der Stellgeschwindigkeiten als auch der maximalen Stromstärken eingehalten werden.According to the present invention, the predetermined limits can be maintained both in the range of the positioning speeds and the maximum current strengths.

Bei dem in Figur 1 dargestellten System sind die Elemente von drei Flugzeugsitzplätzen über einen Datenbus miteinander verbunden. Jeder Flugzeugsitzplätzen enthält ein Bedienungselement 1 , ein Sitz-Steuergerät 2 und drei Antriebs- bzw. Stellelemente 3.In the system shown in FIG. 1, the elements of three aircraft seats are connected to one another via a data bus. Each aircraft seat contains an operating element 1, a seat control unit 2 and three drive or adjusting elements 3.
Bei den Bedienungselementen kann es sich beispielsweise um Taster, Schalter und Chipkartenleser handeln.The operating elements can be, for example, buttons, switches and chip card readers.
Die Sitz-Steuergeräte 2 dienen der Ansteuerung der Stellmotoren 3, sie überprüfen auf gültige Bewegungen, fahren automatisch Positionen und erfüllen ein „Power- Management". Jedes Sitz-Steuergerät 2 hat einen Bus-Controller 4. Außerdem enthält jedes Steuergerät 2 ein Power-Supply 5.The seat control units 2 serve to control the servomotors 3, they check for valid movements, automatically move positions and fulfill a “power management”. Each seat control unit 2 has a bus controller 4. In addition, each control unit 2 contains a power Supply 5.
Der AFDX-Bus ist in den Figuren 1 und 2 mit dem Bezugszeichen 6 gekennzeichnet.The AFDX bus is identified in FIGS. 1 and 2 by reference number 6.
Die Stellmotoren 3 der in Figur 1 linken Sitzgruppe können über die Busverbindung 7 von dem zu diesem Sitzplatz gehörenden Steuergerät 2 (das sich in der Darstellung über den Stellmotoren 3 befindet) angesteuert werden. Wenn dies z.B. in Folge eines abgefallenen Steckverbinders oder Kabelbruchs nicht möglich ist, werden die Stellmotoren 3 von dem in der Darstellung mittleren Steuergerät über die Busverbindung 8 von der anderen Seite angesteuert.The servomotors 3 of the left-hand seating group in FIG. 1 can be controlled via the bus connection 7 by the control device 2 belonging to this seat (which is located above the servomotors 3 in the illustration). If this e.g. is not possible due to a dropped connector or cable break, the servomotors 3 are controlled by the control unit shown in the middle via the bus connection 8 from the other side.
Figur 2 zeigt ein Daten-Ringbussystem mit zwei Steuergeräten 9, drei Bedienungselementen 10 und drei Paaren von Stellmotoren 1 1 von drei benachbarten Flugzeugsitzplätzen. Hierbei sind die Bedienungselemente in den Ringbus mit einbezogen.FIG. 2 shows a data ring bus system with two control devices 9, three operating elements 10 and three pairs of servomotors 11 from three adjacent aircraft seats. Here are the controls in the Ringbus included.
Bei den Stellmotoren 1 1 handelt es sich wieder - wie bei den Stellelementen 3 der Figur 1 - um intelligente Steller, die ständig die Konfiguration an die Steuergeräte übermitteln.The servomotors 11 are again - like the actuating elements 3 in FIG. 1 - intelligent actuators which continuously transmit the configuration to the control units.
Figur 3 zeigt die Stromversorgung einer Doppelsitzanordnung mit je einem Bedienungselement, drei Stellmotoren 13 und je einem Sitz-Steuergerät 14.FIG. 3 shows the power supply for a double seat arrangement, each with an operating element, three servomotors 13 and one seat control unit 14 each.
Alle Stellmotoren 13 und die Bedienungselemente 12 sind durch zwei getrennte Netze mit Strom versorgbar, die entweder von dem in der Figur linken oder dem rechten Steuergerät gesteuert werden. Die Stellmotoren 13 können - wie bei dem in der Figur linken Stellmotor 13 angedeutet ist - einen Schalter 1 5 haben, mit dem sie entweder mit dem einen oder dem anderen Stromkreis verbindbar sind. Zu demselben Zweck können beispielsweise auch Entkopplungsdioden vorgesehen sein. Die Schalter oder dergleichen können auch in den Bedienungselementen angeordnet sein.All servomotors 13 and the operating elements 12 can be supplied with power by two separate networks, which are controlled either by the left or the right control unit in the figure. The servomotors 13 can - as indicated in the left servomotor 13 in the figure - have a switch 15 with which they can be connected either to one or the other circuit. Decoupling diodes can also be provided for the same purpose, for example. The switches or the like can also be arranged in the operating elements.
Die Stromzufuhr 5 der Steuergeräte 14 kann auch ein Multimediasystem, einen PC, Tastatur, Monitor, Lautsprecher und Mikrophon speisen, die in der Figur insgesamt mit dem Bezugszeichen 16 gekennzeichnet sind.The power supply 5 of the control devices 14 can also feed a multimedia system, a PC, keyboard, monitor, loudspeaker and microphone, all of which are identified in the figure by the reference number 16.
Mit Hilfe einer der Steuereinheit 14 befindlichen Software oder durch entsprechende Verkabelung sind die Stellmotoren 1 3 und die Bedienungselemente 1 2 dem jeweiligen Flugzeugsitzplatz zugeordnet. Dies bedeutet, daß die rechte Einheit die zu ihr gehörenden Systemanteile kennt und damit auch weiß, welche zu dem linken Partner gehören. Da alle Systemteile aber eine gemeinsame Bus-Struktur haben, ist das jeweilige Steuerungssystem auch darüber informiert, was gerade auf der anderen Seite geschieht.With the help of software located in the control unit 14 or by means of appropriate cabling, the servomotors 1 3 and the operating elements 1 2 are assigned to the respective aircraft seat. This means that the right unit knows the system parts belonging to it and thus also knows which belong to the left partner. However, since all system parts have a common bus structure, the respective control system is also informed about what is happening on the other side.
Nach einem weiteren wesentlichen Gesichtspunkt der Erfindung werden sämtliche Unstimmigkeiten und Fehler, deren Art und genauer Ort jeweils festgestellt werden, durch ein durch alle Sitzplätze gehendes Bussystem an ein zentrales Gesamtwartungssystem übermittelt, das in Fig. 1 mit dem Bezugszeichen 1 7 angedeutet ist. Damit können alle aufgetretenen Fehler an den Sitzplätzen zentral abgefragt werden. According to another essential aspect of the invention, all Discrepancies and errors, the type and exact location of which are determined, are transmitted to a central overall maintenance system by a bus system that extends through all the seats, which is indicated in FIG. 1 by the reference number 17. This means that all errors that occur at the seats can be queried centrally.
